Komatsu SAA4D95LE-5 is low fuel consumption by total con-

trol of the engine, hydraulic and electronic system.

The newly-developed Komatsu engine enables NOx emis-

Engine speed automatically slows down

when all control levers are set in neutral.

Due to Komatsu’s excellent hydraulics tuning technology, the

machine satisfi es both requests for powerful operation and

Two established work modes are further improved.

P mode – Power mode gives priority to work, while maintaining

fast equipment speed and maximum production and power.

E mode – Economy mode reduces fuel consumption. Speed of

work equipment is almost same as P mode for light duty work.

Operator can select Power or Economy mode using a one-

touch operation on the monitor panel depending on work

load. In addition, operator can select E0 or E1 mode within

E mode depending on work load. The power output will be

reduced when adjust E0 to E1, however, the fuel consump-

tion will be better.

The ECO gauge on the right side of the multi-function color

monitor provides environment-friendly energy-saving opera-

tion. Focus on operation in the green range allows reduction

of CO2 emissions and effi cient fuel consumption.

COMFORT

Newly designed large cab provides

roomy work space and wide legroom.

In addition, large operator’s seat has

a fore-and-aft sliding and a reclining

function.

The automatic A/C has a bi-level

control function to keep cool and

warm respectively. This improved air

fl ow function keeps the inside of the

cab comfort-

able from top

to bottom

throughout the

year. Defroster

function keeps

cab glass clear.

Cab is highly rigid and has excellent

sound absorption ability. Improvement

of noise source reduction and use of

low noise engine, hydraulic equipment,

and air conditioner allow this machine

to generate a low level of noise.

Spacious cab has wide glass area to pro-

vide the operator with excellent visibility.

SAFETY & ICT

The machine is equipped with a ROPS cab (ISO 12117-2) for

excavators as standard equipment. The ROPS cab has high

shock-absorption performance, featuring excellent durability

and impact strength. It also satisfi es the requirements of OPG

top guard level 1 (ISO 10262) for falling objects. Combined

with the retractable seat belt, The ROPS cab protects the

operator in case of tipping over and against falling objects.

A large user-friendly color monitor enables safe, accurate and

smooth work. Improved screen visibility is achieved by the

use of LCD that can easily be read at various angles and light-

ing conditions. The switches are simple and easy to operate.

Industry fi rst function keys facilitate multi-function operations.

Displays data in 12 languages to globally support operators

around the world.

ATTACHMENT

Komatsu-recommended attachment tools for hydraulic excavators

A wide range of attachment tools are provided to suit customers’ specifi c applications.

Komatsu Genuine Attachment Tool

Hydraulic breaker

The hydraulic breaker is an attachment tool used for crushing rock beds and paved surfaces, demolishing

concrete structures, etc. The large gas chamber, ideal gas pressure ratio, and long-stroke piston deliver

a powerful impact force. Since the breaker unit does not require an accumulator, the number of

parts has been reduced, resulting in lower maintenance costs.
